Relinquishing job because the mailbox is locked

I was getting this error constantly when trying to move a mailbox from Exchange 2013 back to Exchange 2010. For the life of me I could not get to the bottom of it then I looked through the event logs and noticed this happening every time the mailbox tried to move as shown below.

(highlighted sections in red) – Which to me looked like there was search issues upon conferring with a colleague it was suggested that the outlook profile has a corrupt index and would need resetting. Easy enough:

fire up a cmd prompt and run outlook.exe /cleanfinders /cleanviews

Give it 5 minutes then try the move again and it went through successfully!
